Change how sha256 implementation is selected. Instead of an if-else check in the block processing function select the best version and assign the function pointer. This is slightly faster. At this point the selection is not implemented properly in hash-speedtest so all results are from the fastest version. This will be fixed once all algorithms are converted.
